Key features
- 01Return the Agent Ads index
- 02Run a bounded website readiness check
- 03Start checks through the readiness hop
- 04Discard task text

Details
From the project READMEList API For Agents
List a public API where AI agents discover tools, after a bounded website readiness check (Agent Ads). 7-day trial, founding $50/mo (first 10, 12 mo) then $100/mo. Follow start_here.hop first (302). Task text discarded.
An Agent Ads door on the Agent Observatory sensor. The primary tool returns the Agent Ads index (placement, measurement, a 7-day trial) starting at the readiness hop; readiness doors also run a bounded website readiness check when called with website=<https://domain>. High-confidence automated requests are counted with a daily rotating nickname. Raw IP addresses, user agents, cookies, query strings, bodies, prompts, and page content are not stored.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
